v Patented Feb. 4, 1930 UNITED STATES PATENT OFFICE JESSE A. B. SMITH, OF STAMFORD, CONNECTICUT, ASSIGNOR TO UNDERW OOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE comzemnn 'rvrnwnirfne AND cARD-PUNGHING MACHINE Application filed February 26,1926. Serial 110.90,?58.

This invention relates to a combined typewriting and card-perforating machine, and particularly to means for coupling the typewriter and the card-perforator for joint operation.

The invention is herein described and illustrated as applied to an Underwood typewriter in combination with a Powerskeypunch, the key-punch being herein called the card-perforator.

These machines are coupled for the purpose of producing a perforated record-card simultaneously with the typing of the record upon a work-sheet in the typewriter. As is well known, these cards are used in making groupings,analyses, tabulations, etc, of the items indicated by perforations in the cards. A line of data under form headings on the work-sheet may include portions which need not be transferred to the record-card. Therefore, while said portions are beingtyped, the,perforator must be inactive. I

The card-perforator has a movable denomination-determining carriage which traverses afield of pins arranged in denominational columns, one pin for each hole-space on the card. The pins, which are aligned over punches, are settable to predetermine -where holes are to be punched, and the car riage has key-controlled plungers operable as digit-selecting means and to effect the setting of said pins.

By means of the usual electromagnetic devices and connections, the pin-setting plungers may be actuated to set pins by operation 1 of the typewriter-keys, the perforator-carriage advancing step "by step, as the pins are set in one denominational column at a time. Instead of controlling the step-by-step moveescapement-mechanism of the perforator, it is desirable that this movement be controlled by the typewriter-carriage through the typewriter-carriage escapement, so that the two carriages may always be in their proper-rela tive positions.

An object of the present invention is to provide improved means whereby the type writer-carriage may positively drive the perforator-carriage in its advance and return ment of the perforator-carriage by the usual movements, said means being further devised to bring into action the perforator-setting mechanism whenever an item that is to be punched on the card is written on the worksheet. Conversely, if anything written on the worksheet is notto be punched, said means shall be effective to suspend the movement of the perforator-carriage and also suspend the operation of the pin-setting plungers. This relieves the operative of the care usually required in operating a foot pedal or other means usually provided for suspending'and resuming the, joint operation of the two machines.

To accomplish this. automatic control, there is provided on each carriage a rack. The typewriter and perforator are placed in suitable positions relatively to each other so that said racks on their carriages may be coupled, preferably by means of a shaft, each end of the shaft having a suitable pinion which meshes with one of the racks. In the array of teeth on the rack in the typewriter- -carriage there are toothless gaps,

said gaps being of predetermined extent and location to correspond with the form on the work-sheet as related tothe form on the card. Because of the toothless gaps in the rack on the typewriter-carriage, the perforator-carriage Will be driven intermittently.

While the typewriter-carriage is moving alone, and the perforater-carriage is stationary, the operative connection between the typewriter-keys and pin-setting plungers must also be broken so that no pins may. be set or indexed by operation of the typewriterkeys while the perforated-carriage is stationary. To break this connection, it is preferable to open a common lead of the circuit that operates the electromagnetic devices by means of whichthe pin-setting plungers are actuated when the typewriterkeys are depressed. To this end, there is provided a switch having a pair of contacts which may be closed and opened, said con,- tacts being in the common lead of the circuit that, operates the electromagnetic devices. To operate this switch there are provided on the side of the typeWriter-carriage-rack suitable cam -projections. These projecthat its endwise movement opens the switch.-

, The bar may be spring-pressed by that part of the switch which it moves, thereby causing it to resume its normal position and allowing the switch to close again as soon as the projection, which has moved it, has passed. The

cam-projections vary in widths to correspond with the intervals during which it is desired to suspend the operation of the pin-settlng plungers.

Due to the toothless gaps in the driving rack on the typewriter-carriage, the perforatorcarriage will be out of the control of said rack when none of the teeth thereof are in mesh with the pinion related to said rack. To preventmovement of the perforator-carriage under this condition so that upon resumption of the joint movements of the two carriages their proper relative positions are assured, means are provided to hold the perforator-carriage when the typewriter-carriage is to move alone. In some cases a springpressed detent suitably applied may be employed to hold the perforator-carriage. Preferably, however, means to lock the perforator-carriage positively are to be used and there is provided a revoluble circular disk having gaps or slots cut in its periphery. This disk is geared to the coupling shaft which connects the racks of the perforator and typewriter carriages, the gearing being of such proportions that the disk is rotated in steps equal to the spacing of the slots. As

the typewriter-carriage is moved, step by step, the disk is caused to rotate, step by step, on an axis substantially parallel to said racks, and at each step presents a slot in the path of tabs extending from the aforesaid rack on the typewriter-carriage. These tabs, properly spaced and proportioned as to width, enter the slots and interlock therewith at predetermined intervals during the movement of the typewriter-carriage, and in this manner hold the coupling shaft. and consequently, the perforator-carriage, during such intervals. A detent applied to the periphery of the disk and co-acting with suitable notches therein, is used to facilitate the alignment of said slots with said tabs. There is sufficient clearance provided between the sides of the slots and said tabs to enable the tabs to readily enter the slots, and the advancing edges of said tabsmay be beveled or tapered to facilitate such entrance. The pertoratorca-rriage need not be rigidly locked in its idle positigns, it being only necessary to prevent undue creeping or displacement of said carriage. 1

The typewriter-carriage-rack, the locking tabs and the switch-operating cam-projections are combined in one unit of control, and meansare provided for-easily attaching and detachlng this unit to and from the typewriter-carriage, because each definite form of work-sheet with its related card-form requires a unit especially adapted thereto in regard to the spacing and widths of the afor said tabs, cam-projections and toothless gaps. Thumb screws are preferably used to secure a unit upon suitable extensions from the typewriter-carriage. The extensions which may project rearwardly from the ends or sides of the typewriter-carriage are spanned by a rail. The unit with its rack bearing at intermediate points upon said rail is mounted adjacent and parallel thereto. As the typewriterarriage moves, the rail rides upon a roll mounted upon the perforator-frame. The roll is located so that it takes up the thrust due to the reaction between the rack and its pinion. Said rail may also be formed as part of the rack or its attachments.

The coupling shaft, the locking disk with its detent, and the switch with its actuating rod, are assembled in a bracket and form a compact unit that may be mounted upon the perforator-framework. The actuating rod for said switch is provided with a holding notch that may interlock with a slotin the casing through which it projects. Said notch will hold the actuating rod to keep the switch contacts open, whenever'it is desired to use the typewriter alone in regular typewriting work. When the typewriter is thus used, the detachable unit may be removed entirely.

An advantage of the present invention is that back-spacing of the typewriter-carriage may be eifected without changing the proper relative positions of the perforator and typewriter carriages. If the typewritercarriage in its last advancing step has moved alone, it may and will be back-spaced alone. It said carriage is moved jointly with the perforator-carriage in the last advancing step, said carriages may and will be backspaced jointly. The usual carriage-return mechanism may be advantageously employed. the speed of the return movement being limited. but not unduly, by the action of the aforesaid locking device that holds the perforator carriage. It will be understood that the return movement of the perforator-carriage is also intermittent and that an inordinate speed of such return movement would put an undue strain upon the locking device. The usual tabulating mechanism may also be employed and may consist either of the standard Underwood column-tabulating mechanism. or may be of the decimaltabulating type. The invention is illustrated as applied to a typewriter having a columntabulating mechanism equipped with the usual braking device to limit the speed of the tabulating movements of the carriage.

The invention is illustrated mainly as worked out for writing a certain form and punching a corresponding card, the card and ment of both carriages of only one step, said joint movement occurring between intervals during which the typewriter-carriage alone moves. In such cases, there is required a single tooth dividing two toothless gaps in the array of driving teeth on the typewritercarriage-rack, and said tooth must drive its pinion and be out of driving mesh therewith in one step. To accomplish this, coupling pinions of five teeth each maybe used, and are satisfactory for any sequence of joint and separate stepping movements of the carriages, said stepping movements being in steps of the usual extent. Pinions of such a small number of teeth are readily obtainable in the open market in the form of a pinionrod, or they may be readily manufactured.

The invention as shown in its preferred form is adapted so that while the typewritercarriage moves in steps of letter-space extent it may drive and move the perforatorcarriage in steps of hole-spacing extent."

This requires coupling pinions of proportionate pltch diameters. The pmion which meshes with the rack on the perforator-car-- riage preferably, but not necessarily, has the same number of teeth as'the pinion meshing with the typewriter-carriage-rack. The linear pitch of the latter rack and its pinion is equal to the letter-spacing pitch of said carriage.

Other features and advantages will hereinafter appear.

N umeral-keys 15 and alphabet-keys *16, when depressed, swing key-levers 17 about a fulcrum 18, to actuate bell-cranks 19, to swing I type-bars 20 upwardly and rearwardly against the front face of a platen 21. The platen is revolubly mounted in the carriage 22, which moves upon carriage-rails 23 and 24 on the main frame 25 of thetypewriter. A worksheet 26 is introduced at the rear of said platen and fed around it by the usual means including feed-rolls 27. Said carriage is urged from left to right by a spring-motor 28 connected to the carriage by a strap 29. The type-bars engage a universal bar 30, movable rearwardly to actuate an escapementrocker 31, carrying escapement-dogs 32, 00- operating with the teeth of an escapementwheel 33 to effect step-by-step letter-space movements of the carriage by the operation of any key or a space-bar 34. The escapement-wheel is connected to and is rotated in one direction by a pinion 35, which is driven by afeed-rack 36 supported by arms 37 pivoted to the carriage-frame.

A tabulating mechanism may be used to advantage in this invention, and is of the'type shown in the patent to H. Crutchley, No. 929,080, dated July 27, 1909, which consists of a tabulator-key 38 pivoted on the fulcrum 18, and provided with a draw link 39 that connects with a rocking frame 40, carrying a series of stops 41.

By depressing said tubulator-key these stops are caused to move into the path of the I for checking the speed of the carriage when tabulating is particularly useful in the present invention, as will be shown later.

Power-driven means for returning the typewriter-carriage may include an electrical motor 43 geared to a clutch-member 44 which is keyed to a shaft 45 on which is slidably mounted a clutch-pinion 46 having clutchteeth to engage said clutch-member 44. Said clutch-pinion meshes at all times with a rack 46 mounted on the typewriter-carriage, and is capable of driving said carriage by means of said rack. The speed of rotation ofsaid clutch-pinion, and consequently the speed of the return movement of the carriage is limited by the requirements of this invention, as will be shown later. A proper limit to said speed is established by a suitable ratio -of gearing between the motor 43 and the clutchmember 44, said gearing being within a casing 43. For shifting the slidable clutch-pinion 46 into and out of engagement with the clutch-member 44, .the usual means, not shown, are employed. Said means and other means, not shown, for line-spacing the platen are shown in the pending application of Alfre d G. F. Kurowski, Serial No. 41,507, filed July 6, 1925 (now Patent No. 1,679,727, dated August 7, 1928). A carriage-return-key 47 (see Figure 3) is provided to engage the carria e-return mechanism.

trip-key 48 is provided at the typewriterkeyboard, and is used to start a perforating cycle of the card-perforator. Said card-perforator is the well-known Powers key-punch. This perforating cycle must precede the return of the perforator-carriage. During this cycle a blank card 49 is picked from a stack 50 by means of a reciprocating picker 51 and pushed through a one-card aperture 52, and thence to the feed-rolls 53, 54 and 55. These rolls carry thecard into punching position,

determined by stops 56. Inthis position the' card overlies a die-plate 57, which may co-act with punches 63, as will be shown. The feedrolls 55 bear upon the card with limited pressure, so that they may slip over the surface 1 of the card'when it reaches the stop 56."

The upper ends of the punches are guided by holes in the plate 64 supported by a machine-frame A. The punches are prevented from falling through by having enlarged heads 65. The lower ends of the punches are guided by holes in the bar 66. Said. bar 66 guide the lower ends of the pins.

and the die-plate 57 are part of a frame 67,

which after receiving a card is moved upward, and presents the cards to the punches.

This upward movement effects perforation of the card whenever punches are held down in a manner to be shown presently. Punches notheld down are carried upward by the card. After a card is perforated, it remains in place under the punches until another perforating cycle is initiated. At the beginning of such a cycle, the stops 56 are withdrawn by a cam device, not shown, and the feed-rolls 55 then pass the card to rolls 68, and thence into a receptacle 69. Each punch has aligned to it one of the pins 70 which may be pushed down and latched, so that its lower end abuts the punch and holds it down as the card moves upward and is pierced by said punch.

The pins and punches are arranged in columns of 12 each, andeach column of pins is provided with a latch-bar 71 having suitable edges to interlock with edges 72 of the pins 70 to hold down a pin when depressed. Each latch-bar and its associated twelve pins are devised to co-act in the manner wellknown in the adding machine art, so that the depressed pin or pins are restored by the depresslon of another pin or pins in the same column. When. the latch-bar is withdrawn from a depressed pin, the pin is restored by a spring 73 which presses the pin upwardly until a collar fastened to the pin strikes a plate 74. The lower end of the spring reacts against the plate 7 5. Said plates 74 and 75 are supported by cross-bars 75 fastened to the machine-frame A, and have holes which The upper ends of said pins are guided in holes in a plate 76 supported by cross-bars 77 fastened to the machine-frame A. The latch-bars 71 are slidably supported in the cross-bars-77 and are pressed against the pins by springs 78.

To eifect setting of the pins, the perforator is ordinarily provided with twelve manually operable keys. These twelve .keys correspond to the twelve hole spaces of each column. Co acting with said keys are twelve pin-setting plungers 79 arranged to tIfiV-J erse, 111 a carriage 80, the blank of'sett'ing pins 70. Said carriage has rolls 81 which retain and guide it upon rails 81 supported by the machine-frame A.

,As shown in the pending application of Alfred -G. F. Kurowski, ,No. 48,723, filed 1 August 7, 1925 (now Patent No. 1,684,155,

84 (see Figure 3), and the plungers thereof are operatively connected to the pin-setting The -flexible push-wires 85 are enclosed in flexible sheaths 87. A universal bar 88 spring-pressed against the vertical arms of the bell-crank levers 86 keeps the pin-setting plungers normally up.

Each of the solenoids 83 is in a normally open electrical circuit which includes a source of current 92 and a pair of separated contact devices 93 (see Figure These contact devices underlie the typewriter-keys 5 and 16, and are arranged within a case 4 (see Figure 1) through the top of which extend plungers 95, by means of which the typewriter-keys, when depressed, close said contacts to energize the solenoids. When typing acharacter represented'by two holes in the card, the corresponding typewriter-key closes two sets of contacts 93*" (see Figure 10), so that two solenoids are energized and two pins set. The wires connecting the contacts on the typewriter and the solenoids on the perforator are gathered in a cable 96. V

The trip-key 48, like the typewriter-keys, is effective by means of contacts 48* to actuate a solenoid '97 (see Figure 10) within the case 84. A plunger 98, by means of a flexible push-wire within a'sheath 99, is capable when actuated by said solenoid 97 of operating a clutch-mechanism to a source of power, not shown, to start-a cycle of the perforator. The details of this clutch-mechanism and its mode of operation are shown in the patent to Lasker, No. 1,352,006, dated September 7, 1920. The plunger 98, of the present invention, re places the controlling key shown in said patent to Lasker. I mechanism connects the machine-shaft 100 to a continuously-rotating motor-driven disk, not shown. At the end of one revolution, said machine-shaft is automatically disconnected from the driving disk.- During this revolution the feed-rolls 53, 54,55 and 68 are rotated by means of the gear 101 on the shaft 100. The frame 67in suitable guides is moved up and down by means of arms 102, extending from the ends of a rocker bar 103 pivoted at each end tov the machine-frame A at 104. Said rocker bar is operated by means of an arm 105 projecting from the middle thereof, and which engages a grooved face cam 106 by means of a follower roll 107. After the perforating cycle, return-of the pin-setting carriage is effected in a manner that will be shown presently, the return being started by depression of the carriage-return key 47, which engages the prevlously-mentioned carriage-return mechanism, and, during this return, pins are restored by means described in the aforesaid pending application, N 48,723,1elating to a combined type writer and card-perforator. Said means include a roll 108 which is carried by the pin- Operation of the clutch-' on the'machine-fra'me A apart from said pinsetting carriage 80 and are thus traversable by said roll 108. For shifting said roll from ineffective to effective position it is mounted upon a lever 110, pivoted upon the pin-setting carriage and connected to an arm 111 also pivoted upon the pinsetting carriage. During the final advance movement of the pinsetting carriage, said arm 111 is rotated when it meets an extension 112 from the machineframe A. Said arm 111 is then caught and held by a latch 113 pivoted upon the pinsetting carriage. In this manner, the roll 108 is caused tobe depressed and held in a position where it is effective to actuate the pin-restoring levers 109 by and during the return movement of the pin-setting carriage 80,'said roll 108 traversing said levers 109.

Said pin-restoring lev'ers 109, when pushed I aside by said roll, in turn push their respective latch-bars '71 aside to release pins that have been set. At the end of the return movement of the pin-setting carriage the latch 113, when it meets an adjustable stop 114, is rotated and withdrawn from the arm 111. A suitable spring, not shown, then re stores the arm 111, causing the roll 108 connected therewith to be raisedout of engagement with the pin-restoring levers 109.

The perforator-pin-setting carriage 80 is driven by the typewriter-carriage 22. To this end, a rack 115 is mounted upon a rail 156 which spans extensionsllG projecting rear- -wardly from the typewriter-carriage frame 117. In some classes of work, as illustrated by'Figures 11 and 12, it is necessary for the perforator-carriage to be stationary while which there are no corresponding spaces on the card may pass the printing point. In order that the typewriter-carriage under these conditions shall not drive the perforator-carriage, the rack 115 is provided with toothless gaps 118 (see Figure 4) in its array of driving teeth. The extent of these gaps corresponds to the number of steps the typewriter-carriage is to take alone while the perforator-carriage is idle. A pinion 119 meshes with said rack and the number of' teeth of said pinion is such that a single driving tooth on the rack cannot drive it through more than a certain minimum number of steps determined by the arrangement of the work-sheet and the card-forms. The illustrative forms in Figures 11 and 12 are so arranged that intervals, during which the typewriter-carriage alone moves, are followed by stages of joint movement of both carriages of at least four steps. In some cases where the movement of the typewritercarriage alone must be followed by movement of only one step of both carriages, the pinion 119 must have a limited number of teeth so that a single driving tooth on the rack can only rotate said pinion through one step. It has been found that a five-tooth pinion will meet this requirement, and is illustrated in Figure 5. \Vhere the minimum number of steps of the oint movement of both carriages following a movement of the typewriter-carriage alone may be more than one step, a pinion with a proportionately larger number of teeth may be used.

The pinion driven by the rack 115 is mounted and keyedto a shaft 120, which extends rearwardly toward the perforator-carriage. Said shaft rotates in a bracket 121 mounted upon a platform 122 of the perforator-framework. Upon the rear end of said shaft is mounted and fastened a pinion 123 which meshes with a rack 124 on the perforator-carriagev 80. forator-carriage by means of tabs 125, extending from a bar 126, fastened upon studs 127 which support the front rolls 81. The carriage 22 is fed letter-space distances and the pitch of the teeth of the rack 115 is made equal to said carriage-feeding distances, so that the teeth of the pinion 119 and the teeth of the rack 115 will always assume the same tooth relations at the end of each letter-spacing-movement, to promote the reengagement of the pinion and rack.

It will be seen from Figures 6 and 7 that when no teeth of the rack 115 are in driving contiguity to the pinion 119, the pinion is not held by said rack 115, and consequently the perforator-carriage is free to move idly. To prevent such idle movement, meansare provided to hold the perforator-carriage when the pinion 119 is not controlled by lts rack 115. To this end, there is mounted upon the shaft .120, a miter gear 128 which meshes with another miter gear 129. Said miter gear 129 rotates upon a stud 130 secured in an ex: tension 131 of the bracket 121. Fastened to said miter gear 129 is a disk 132 having slots 133 in its circumference. The number of said slots is equal to whatever number of teeth the pinion 119 has. For example, in Figure 2, a five-tooth pinion 137 has a corresponding disk 138 with five slots 139. The disk 132 or 138 is so set that one of the slots is al- Said rack is fastened to the per-.

ways presented in the path of tabs 140 on one edge of a channel-shaped bar 141 fastened to the rack 115. One of these tabs, as the typewriter-carriage moves along, enters one of the slots 133 and interlocks therewith during each interval in which the typewritercarriage moves alone. Interlocking of the tabs 140 with one of the slots 133 causes the disk to be held substantiallyimmovable, and in this manner prevents movement of the perforator-carriage which is thus held until the rack 115 rotates its pinion again. At the beginning of the first step of a stage in which both carriages move jointly, the escaping edge 142 of a tab 140 is clear of the disk 132, as

seen in Figure 9. Figure 8 shows the approaching edge of the tab 140 just about to interlock with the disk 132 .as soon as a last driving tooth 143 of a group of teeth is out of driving contiguity with said rack. Figures 6 and 7 show a tab 140 fully interlocked with the disk 132 to hold the pinion 119, which, it will be seen, would otherwise be free to rotate idly. To facilitate the alignment of a slot 1.33 or 139 with a tab- 140, a spring-pressed detent arm 144 having a roll 145 is provided and mounted on the bracket 121. Said roll co-acts with notches 146 which may be formed at the ends of the slots 133.

In order that no pins may be set by operation of the typewriter-keys when the typewriter-carriage alone moves, means are provided to break the operative connection between said typewriter-keys and the perforator-setting mechanism. To this end, there is interposed in one of the leads to the branch circuits for the electromagnetic devices, operable by the typewriter printing keys, a contact device which may be opened and closed. Said contact device includes a pair of contacts 147, one of which is mounted on a resilient conductor 148 which may be flexed to open and close said contacts 147 (see Figure 10). The other contact may be relatively fixed and said fixed contact and said conductor properly mounted and insulated are within a casing 149 fastened against the side of the bracket 121. Said contacts are connected to the lead 147 by meansof a Wire 148 A push-bar 150 passes through slots in the walls of said casing, and, by means of an insulated button 150 thereon, may push against the conductor 148 to open the contacts 147. Stop pin 151 in push-bar 150 retains said bar when the contacts are closed. To open and close said contacts there is provided a series of cam-projections 152 also formed 'upon the channel-shaped bar 141, but on the edge opposite the edge upon whicli the tabs 140 are formed. The width and spacing of these cam-projections is such that said projections push aside said bar 150 and open the contacts 147 during the intervals when the typewriter-i carriage alone moves. Figures ,8 and 9 each includes a plan view of said cam-projections and the contact devices operable thereby. Figure 8 shows the contacts as having been opened at the end of the last step of a stage of joint movement of both carriages to be followed by an interval during which the typewriter-carriage alone moves. The dwell 152*- is of such width as to keep the contacts open throughout said interval. Figure 9 shows the contacts as having been closed at the end of the last step of an interval in which the typewriter-carriage alonemoves, said interval to be followed-by a stage of joint movement of both carriages. The rounded end of the push-bar 150 at the end of the last step of said'interval has dropped off the dwell 152 thereby permitting the resiliency of the conductor 148 to cause the contacts 147 to close.

The bar 141 with its tabs 140 and camprojections 152 is assembled as a unit with the rack 115 by means of lugs 154 formed upon said rack and thumb screws 155. Said unit is detachably mounted on the rail 156 spanning the extensions 116. The rack 115 or its attached bar 141 may be supported by a roll 157, bearing against the rail 156 upon which said rack rests to prevent displacement be-- tween the rack 115 and its pinion 119. The

roll 157 rotates on a stud 158 fastened in a projection on the bracket 121.

The pinions 119 and 123, carriage-couphng shaftl20 and controlling devlces assembled on the bracket 121 from a compact unit. "A

paper-table 159 of a type regularly supplied with typewriters keeps the W0rksheetclear of the coupling mechanism.

The perforator-carriage is under the control of the typewriter-carriage during both advance and'return movements, and the previously-mentioned carriage-return mechanism, when returning the typewriter-carriage 22, also returns the performator-carriage. The return of said perforator-carriage, because of the toothless gaps in the rack 115, is in intermittent stages defined by intervals during which the typewriter-carriage alone moves. These stages and intervals correspond to the stages and intervals in the advance movements'of said carriages. On account of said intermittent movement of the perforator-carriage, the speed of the return movement of said carriage should be limited to assure proper operation of the interlocking disk 132 and the tabs 140. A surtable speed of return movement may he established by a suitable ratio of the gearing within the case 43*, as already explained. Furthermore,

the perforator-carriage need not be rigidly locked during its idle intervals, and accordingly slots'133 may have clearance about the tabs 140, as shown in Figure 13, to facilitate the interlocking of the tabs with said slots. The speed of the tabulating movements of the typewriter-carriage may also be controlled to assure proper operation of the disk 132 and the tabs 140 during tabulating. For this purpose the usual braking device which is part of the tabulator-mechanism, as already explained, is useful.

The diameters of the pinions 119 and 123 are proportioned so that while the typewritercarriage moves in steps of letter-spacing extent the perforator-carriage'is driven in steps of hole-spacing extent. Pinions of a small number of teeth such as 137 and 136 of Figure 2 have thei i diameters similarly proportioned and as s own may be part of the shaft 120 retained by collars 161. V

The push bar 150 is provided with a notch 160 that may interlock with the casing 149, so that said bar may be held and secured in a position to keep the contacts 147 open whenever the typewriter is used alone in regular typing work. When the typewriter is thus used alone, the unit formed by the rack 115 and bar 141 may also be completely removed.

It being assumed that the carriage 22 has been shifted to the extreme right by the power-driven carriage-return devices, and the platen and work-sheet 26 line-spaced for typing a new line as the last line entry on the sheet, as indicated at 162, Figure 11; the punch-indexing carriage 80 shifted leftward, so that the series of punch-indexing pins are vertically aligned over a predetermined .141 having no cams 152 at this point to engage the shiftable bar 150, the contacts 147 are closed and the punch-indexing solenoids are in a closable circuit with the closed terminals 93 under each The depression of a key 15 in typing the numeral 7 as the first character of a line, simultaneously closes the circuit through the terminals 93 to energize a solenoid 97 to depress an indexpin or pins 70 having a value corresponding to the numeral typed. The renumeral-key 15.

lease of the key 15 effects a carriage-feeding movement of the, typewriter-carriage in the 211511211 manner and the letter-space movement thereof rotates the pinion119 to drive the shaft 120 and the gear 123 in train with the rack 124 of the carriage 80 and shift the twelve pin-setting plu'ngers) 79 to the next row of adjoning indexing pins 70. The other numerals 8,9, 5,6, 3, 2 are successively typed in the Policy column, and the equivalent numerical values areprogressively indexed over the punches 63. The next column under Kind includes four characters, and. as this particular card-record includes all four characters, the full letter-space area of this distance.

&

. typed characters.

After the typing of the last character 3 in the Agency column the typewriter-ca rriage spaces to the first entry position in the Deb. No. column. The pinion 119 is free of the last tooth 16-1 of the rack-section 168, the first tab 110 on the bar 141 has passed into a peripheral groove in the disk 132, and, during the typing of the entries in the Deb. column the pinion 119 is positively detented, the carriage 80 remains stationary and the switchbar 150 has been shifted to open the circuit to the pin-setting solenoids. Hence, during the typing of the numerals in the Deb. column the feeding of the carriage 80 and the setting of the punclrindexing pins are prevented and the entries typed upon the work-sheet 26 are not recorded by the punch-indexing mechanism. This control of the carriage and the punch-indexing mechanism takes place automatically during the course of typing, and without any attention on the part of the operator.

In the next adjoining column, the amount of insurance'to be typed is limited by the width of the corresponding card-column in the present instance to six figures, as: 999999 dollars, but the letter-space area of the column provides for typing a grand total of 999999999 dollars, as shown at Figure 11; consequently, there will be a blank column space of not less than three letter-space disvtanccs at the left of the amount typed in a column. As this non-typed space in the Amount column ad oms the non-punch space in the Deb. column, to condense the punch? iugs on the card 49, the left-hand gap 118 in Figure 4 has a continuous gap equal to six letter-spaces, as indicated at Figure 11., three spaces for the typing of the-Deb. entry and three spaces to be skipped as in tabulating to the highest denomination in the first typed entry in the Amount column where the ,tooth 165 of the group of three teeth on the rack 115 has engaged the pinion 119, the associated tab 140 has released the disk 132, and-the cam 152 has released the bar to hole-space the carriage 80'until the 50000 entry in the Amount column is typed, when the pinion 119 enters a gap 118' in the rack teeth, a tab 140 engages the disk 132, the cam 152 opens the circuit-controlling terminals 147, and the' carriage 80 remains stationary during the feeding movement of the typewriter-carriage through two letter-space distances, as indicatedat-Figure 11, between the Amount and Premium columns. Similarly, non-feeding spaces for the carriage 80 are provided during the continuous feed of the carriage 22, three letter-spaces between the Premium and Disability columns, and three letter-spaces between the Disability and Indemnitv columns, making a total of fourteen letter-space distances during the typing of this single-line entry upon the work-sheet 26 where the feed of the carriage 80 is interrupted. and which interruptions eliminate from the card fourteen records that are only essential for the typed record on the worksheet 26. This differential feeding movement between the two carriages 22 and 80 provides that the card 49 may be fourteen or more letterspace distances shorter than the typed line on the work-sheet 26, through the elmination of blank or non-punch spaces upon the card heretofore necessary, as where the two carriages were positively joined by a train of mechanism. a

From the foregoing description it will be understood that with-the mutilations in the teeth of the rack 115, the sequence of the tabs 1 10 and of the cams 152 are predetermined by the character and style of the worksheet to be typed upon; that said rack 115 and bar 141 carrying the tabs and cams are a unit of assembly, and become a controller for the travel of the punch-indexing carriage 80; that this carriage-controlling unit may be attached, detached or superseded at will by another unit, when the form of worksheet requires a change in the co-operative feed'of the two carriages; that two co-operating carriages are provided, one carriage having a positive continuous feed, and the other carriage having an intermittent or broken feed; and that one carriage has a means effective during the travel thereof, to render the other carriage operative and inoperative to be fed in unison'therewith, according to the typing plan of the worksheet.
